Adjudication Timeframes

A Process Governed by Strict and Unforgiving Deadlines

Adjudication under the Building Industry Fairness (Security of Payment) Act 2017 (Qld) (the BIF Act) delivers speed because it imposes speed. Every step in the process, from the payment schedule to the filing of the application, the response, the determination, and payment, is governed by statutory deadlines measured in business days. Miss a deadline and the consequences are severe: a respondent may become liable for the full claimed amount as a debt due, and a claimant may lose the right to adjudicate altogether. Understanding the timeframe framework is therefore not academic. It is the difference between recovering payment and losing it, between a viable defence and a deemed liability. This page explains the critical deadlines under the Queensland framework; equivalent security of payment legislation in other states and territories imposes its own, sometimes different, timeframes, and the current Act and the actual dates must be checked in every case.

At Construction.Lawyer, deadline management is built into every adjudication matter we run. Our dual-qualified engineer-lawyers map the applicable dates at the outset of every engagement, because in adjudication the calendar is as important as the merits.

The Payment Schedule Deadline

The first deadline in the sequence falls on the respondent. When a claimant serves a valid payment claim complying with section 75 of the BIF Act, the respondent must generally give a payment schedule by the earlier of the deadline stated in the contract and 15 business days after receiving the payment claim. The schedule must identify the payment claim, state the scheduled amount, and set out the reasons for any difference between the scheduled and claimed amounts.

The consequences of missing this deadline are dramatic. A respondent who fails to serve a payment schedule within time becomes liable under section 77 of the BIF Act for the full claimed amount as a debt due, recoverable in court, and may have no right to lodge an adjudication response if the claimant proceeds to adjudication. We advise every head contractor and principal to treat the payment schedule deadline as immovable: diarise it on receipt of every payment claim, and escalate to legal review well before it expires. Our guide to adjudication responses explains how the payment schedule shapes the entire defence.

The Three Application Filing Windows

The claimant's deadline for lodging an adjudication application depends on what happened after the payment claim was served. There are three trigger events, each with its own filing window:

First, where a payment schedule was received but the scheduled amount is less than the claimed amount, the application is generally due within 30 business days after receipt of the payment schedule. Second, where the respondent served a payment schedule but failed to pay the scheduled amount by the due date, the application is generally due within 20 business days after the due date for payment. Third, where no payment schedule was given and the claimed amount was not paid, the application is generally due within 30 business days after the later of the payment due date and the last day on which the schedule could have been given. The current Act and the actual dates must be checked before filing, as the legislation and its interaction with contract terms can affect the calculation.

These windows are jurisdictional. An application lodged after the applicable window closes is invalid regardless of the merits of the claim, and an adjudicator faced with an out-of-time application has no power to determine it. Claimants must therefore track the trigger event carefully from the moment the payment claim is served, because the clock starts running on different dates depending on which scenario unfolds.

Calculating Business Days Correctly

Filing windows under the BIF Act are measured in business days, and miscounting is a common and fatal error. Business days generally exclude weekends, public holidays, and the statutory shutdown period over Christmas and New Year, a period that catches out many parties whose deadlines fall in December and January. The date of receipt of a document is generally not counted, with the count commencing on the following business day.

Public holidays differ between states and even between regions within Queensland, and the correct count can depend on where and how documents were served. We verify every date calculation against the current Act, the relevant public holiday calendar, and the facts of service before advising on a filing deadline. A claimant who miscalculates by a single day can lose a seven-figure claim; a respondent who miscalculates the payment schedule deadline can incur a deemed liability for the full amount. There is no margin for error.

Response and Decision Periods

Once an application is lodged with the Adjudication Registrar and referred to a registered adjudicator, the respondent's opportunity to lodge an adjudication response is governed by the BIF Act, and whether a response is permitted and the applicable response period depend on the Act, including whether the claim is treated as a standard or complex payment claim. Complex claims, generally those above a statutory threshold, attract longer response periods, and the adjudicator may in limited circumstances allow further time. The current Act must be checked in every case.

The adjudicator must then deliver a written determination within the statutory decision period, again depending on whether the claim is standard or complex, with limited provision for extension by agreement. The determination must state the adjudicated amount, the date on which it is payable, and the apportionment of the adjudicator's fees. From lodgement to determination, the entire process is designed to conclude within weeks rather than the months or years litigation would require, which is precisely why the deadlines are so tight and so strictly enforced.

The Five-Business-Day Payment Window

Once a determination is issued, the respondent must pay the adjudicated amount within five business days of receiving the determination, or by the later date fixed by the adjudicator. This is the point at which adjudication's teeth become visible: the obligation to pay arises immediately, even though the determination is only interim binding and either party may later pursue final resolution through litigation or arbitration.

If the adjudicated amount is not paid, the claimant may request an adjudication certificate from the Adjudication Registry and file it in court, where it is registered as a judgment debt enforceable through garnishee orders, charging orders, writs of execution, and winding-up proceedings. The enforcement process is explained in our guide to adjudication enforcement. Respondents should also be aware that enforcement can be swift, and that the grounds for resisting it are narrow.

Consequences of Missing Deadlines

The BIF Act treats its deadlines as substantive, not procedural. For respondents, missing the payment schedule deadline triggers deemed liability for the full claimed amount under section 77 and may extinguish the right to respond to an adjudication application. Missing the response deadline means the adjudicator may determine the application on the claimant's material alone, with predictable results. Missing the five-business-day payment window exposes the respondent to judgment-debt enforcement and, in winding-up scenarios, to serious credit and solvency consequences.

For claimants, missing the applicable filing window is fatal to the application, leaving only the slower and more expensive path of court proceedings to recover the debt. Claimants also face practical deadlines in assembling evidence: a rushed application prepared in the final days of a filing window is rarely a strong one. Both sides benefit from engaging advisors the moment a payment dispute emerges, not when a deadline is imminent.

Practical Deadline Management

Disciplined deadline management is the hallmark of successful adjudication practice. Our recommendations are straightforward. Diarise every payment claim the day it is received, with the payment schedule deadline calculated and verified immediately. Track the trigger event after each payment claim so the correct filing window is identified at the outset. Build in internal deadlines several business days ahead of the statutory ones, allowing time for review, signature, and service. Retain proof of service of every document, because the date of service often determines the date the clock starts.

Above all, seek advice early. When we are engaged at the payment claim or payment schedule stage, we map the entire deadline framework for the matter and manage it on our clients' behalf, removing the risk of a catastrophic oversight. The cost of this discipline is modest, as our guide to adjudication costs explains, compared with the cost of a missed deadline, which can be the full amount in dispute.

Frequently Asked Questions About Adjudication Timeframes

How long do I have to lodge an adjudication application? It depends on the trigger event. Where a payment schedule was received but the scheduled amount is disputed, generally 30 business days after receipt of the schedule; where a scheduled amount was not paid, generally 20 business days after the due date; and where no payment schedule was given and the claimed amount was not paid, generally 30 business days after the later of the payment due date and the last day on which the schedule could have been given. The current Act and the actual dates must be checked before filing.

When is a payment schedule due? Generally by the earlier of the deadline stated in the contract and 15 business days after the payment claim is received. Missing this deadline exposes the respondent to liability under section 77 of the BIF Act for the full claimed amount as a debt due.

How are business days counted? Business days generally exclude weekends, public holidays, and the statutory Christmas shutdown period, and the day of receipt is generally not counted. Public holidays vary by location, so the count must be verified against the facts of service and the current calendar. Miscounting is a common and fatal error.

How quickly must an adjudicated amount be paid? Within five business days of the respondent receiving the determination, or by the later date fixed by the adjudicator. If it is not paid, the claimant may obtain an adjudication certificate and enforce it as a judgment debt. See our guide to adjudication enforcement.
